THE SIGMA Prime Lenses - Test Review

By Alfonso Parra AEC, ADFC
In this article we are going to study the set of Sigma prime cine lens that offers the focal lengths 20mm, 24mm, 35mm, 50mm and 85mm at the moment of the test.
The study focuses on every aspect related to the image quality provided by the lenses, such as the resolution, color, Bokeh or spatial construction, among others. We used the last Red One Weapon 8K
camera recording in 4kHD Raw format, 8:1 compression at 25pfs and 1/50 shutter speed. The analysis of the different tests is made under theoretical considerations: we worked on resolution and color charts and then we analyzed with the Imatest, ImagJ or Color Inspector programs. We used different light sources adjusted with the Sekonic C700 spectrometer and the Sekonic l-588/Cine light-meter. In order to study the material we used Davinci, Prelight and Scratch.
